Fp green 73hta
The HTA green has a 73mm HTA compressor wheel, enabling it to flow 54-56lbs a min. FP said that on the 2.0 with Magnus IM and ported HTA Green and ported Stock Manifold they saw 56lbs a min. Wonder what it would flow with head work and a sick Full-Race Stock twin scroll header! lol
The Red does have the 76mm HTA compressor wheel. It was the very first HTA turbo that FP made. After that they did the HTA35R, HTA30R etc... The Red that FP played with at the end of the developmental stage on a 100mm crank setup flowed 64lbs a min on 36lbs of boost then tappered to 28-29lbs of boost at 7600rpms. That setup put down over 550hp/500tq on a mustang dyno.
So yes they both have HTA wheels; FP made the green for stock bottom end guys wanting a 450hp turbo. The only dif between the HTA Green and red is the 73mm and 76mm compressor wheels. Hope that answered your question.

That is actually a good question that I'm not sure has been properly answered (maybe one of the ER guys can clear this up). I have heard it stands for High-strengthened Titanium Alloy, but I've also seen a post that states that each of the letters designates a change to the wheel technology. In that post it is also mentioned that those designations are internal to FP, but I'm not sure if either of those are truly the case.
The wheel is supposedly lighter but it does provide a faster spool than a similar, non-HTA.

well good to know it isn't well known across the board then!
